Requires use of merchant category codes for purchases of firearms and ammunition.

This bill requires payment processors (merchant acquirers) to assign a specific international merchant category code for firearms and ammunition businesses starting May 1, 2027. It directly affects firearms merchants in New Jersey whose primary sales revenue comes from firearms, ammunition, or firearm accessories within the state. The law authorizes the Attorney General to enforce compliance, imposing a $10,000 civil penalty per violation if businesses fail to correct issues within 30 days of notice. Violations must be self-corrected by the business before penalties apply, with no private lawsuits allowed.
